This article is a collection of molecular pathology tests. It is not meant to be complete list. It is there to give a flavour of what is out there and how things are done.
Hereditary
Tests for hereditary conditions:[1]
| Target | Technique | Disease | Notes |
|---|---|---|---|
| F2[2] | PCR | thrombophilia | see Risks for VTE, done together with F5 |
| F5[3] | PCR | thrombophilia | see Risks for VTE, done together with F2 |
| HFE[4] Cys282Tyr, His63Asp | PCR | hemochromatosis | - |
| RYR1 | PCR & sequencing | malignant hyperthermia | anesthetics |
| APOA1, TTR, FGA, LYZ | PCR & sequencing | herediary amyloidosis | |
| HBA | PCR | Alpha thalassemia |
Lymphoma
Tests for lymphomas:[1]
| Target | Technique | Disease | Notes |
|---|---|---|---|
| BCL2 | PCR | follicular lymphoma vs. follicular hyperplasia | |
| several | Southern / PCR | T cell neoplasia | |
| Ig heavy chain, Ig light chain | Southern / PCR | B cell neoplasia | |
